The supplier reports 3D design, ODM, OEM, and multiple customization services, as well as new-product activity during the past year. It has stated tile-adhesive production information, in-stock capability, peak-season fulfillment within 15 working days, and export experience of five years, with exports representing 71%–90% of total sales. However, certification ownership, quality assurance status, raw-material traceability, valid manufacturing-capacity contracts, and fire-drill status are not established. After-sales complaint handling has a procedure but lacks written records. The supplier reports no overseas warehouse, showroom, agent or branch, or offline trade-show participation, and its overseas-service country count is stated as zero.

Supplier typeThe supplier is explicitly described as a manufacturer specializing in dry-mixed mortar, ceramic tile adhesive, and cement products. Its stated business scope also includes technology development, new-material research and development, environmental consulting, and related product sales, indicating a manufacturing-led materials supplier with supporting technical activities.

R&D capabilityThe supplier reports new products during the past year, technology development and new-material research activities, 3D software design services, ODM capability, and OEM service for well-known brands. It lacks an available SDK, but the broader evidence explicitly supports active product and technology development.

Production capacityThe supplier identifies annual tile-adhesive production of 1,000,000 tons, reports in-stock capability, and states that peak-season orders can be fulfilled within 15 working days. It is also described as a manufacturer, although the status of a valid manufacturing-capacity contract remains unknown.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, 3D software design services, and ODM services. These multiple stated service modes provide direct evidence of broad customization capability.

Product Q&A

Q:What is the difference between thin-layer and thick-layer anti-crack mortar? Which one should I use?

It depends on application thickness and where it is used. Thin-layer (within five millimeters) is for exterior insulation finish, ALC wall anti-crack, and old wall renovation with embedded mesh. Thick-layer (above five millimeters) is for walls with larger deviation that need leveling before anti-crack treatment. Simply put: thin-layer for insulation walls and mesh reinforcement, thick-layer for uneven substrates needing leveling first.

Q:After exterior insulation with EPS or rock wool boards, is anti-crack mortar mandatory?

Absolutely. Without anti-crack mortar and mesh over insulation boards, the finish layer will crack extensively under sunlight and temperature changes, or even cause insulation boards to fall off. Anti-crack mortar is the protective finish layer of the insulation system. Embedded mesh disperses stress and resists cracking an essential step in insulation projects.

Q:How to prevent cracking at new-old wall joints and groove repairs?

These areas have inconsistent shrinkage and are most prone to cracking. Solution: apply local mesh at joints and grooves, then trowel anti-crack mortar and embed the mesh. The mesh acts like a "skeleton" holding the mortar together, preventing cracks from expanding. Note: mesh should overlap by at least ten centimeters, pressed flat and compacted, with no mesh exposed.

Q:My old exterior wall has many hairline cracks. Can I apply anti-crack mortar directly?

No, do not apply directly. First remove the old surface completely to expose a firm substrate and clean off dust. For larger cracks, cut a groove and fill first. Then apply thin anti-crack mortar with embedded mesh, and finally apply exterior paint. Direct application will result in poor bonding between old and new layers cracking and peeling will recur before long.

Q:How long after applying anti-crack mortar can I paint?

Generally, the next step can proceed after one day, depending on weather and thickness. Under normal dry conditions at room temperature, the mortar basically hardens within one to two days. However, before formal painting, it is recommended to cure for at least seven days to allow full hardening, stable strength, and reduced moisture content otherwise the paint may peel or discolor. During curing, avoid rain, direct sunlight, and frost.
